Heterogeneous parallel computing in HTML5 web browsers

WebCL 1.0 defines a JavaScript binding to the Khronos OpenCL standard for heterogeneous parallel computing. WebCL enables web applications to harness GPU and multi-core CPU parallel processing from within a Web browser, enabling significant acceleration of applications such as image and video processing and advanced physics for WebGL games. WebCL has been developed in close cooperation with the Web community and provides the potential to extend the capabilities of HTML5 browsers to accelerate computationally intensive and rich visual computing applications.

FAQ

Q: Does WebCL require an expensive, high-end GPU?A: No. In fact, it doesn't require any kind of GPU. Running WebCL kernels on the CPU is a perfectly valid scenario, and yields significant speed-up over JavaScript.

Q: Does WebCL make Facebook run faster on my browser?A: No. It has no effect on pages that don't use it.
